The problem was an older top-freezer fridge that would freeze its coils behind the back wall of the freezer compartment every 4-6 months or so. I tried defrosting it manually but it would end up freezing over again until the fan could no longer move, which would prevent the lower fridge compartment from cooling.The way most of these top-freezer refrigerators work is that the coils that remove heat are located behind the back wall of the freezer. These remove heat from the freezer compartment and there is also a fan that circulates the cold air down to the fridge compartment. However, these coils also freeze moisture from the air so they build up ice on the coils, so there is a defrost function that periodically melts the ice using a heating unit. The defrost heater runs depending on a thermostat attached to the coils (this part) and a defrost timer part, usually located in the fridge control section.In the case of the fridge I was working on, the original thermostat had come apart and the top part had completely popped out of the metal casing. I wired a replacement thermostat in place of the original thermostat and also pre-emptively replaced the defrost timer controller using this part.The defrost timer was located in the light bulb compartment at the top of the fridge compartment. After popping that off, the time is connected with slide-on metal quick connects so the old one is easily removed and then this new replacement attached in its place. Took about 5 minutes.So far so good, it has been several months and the freezer has not frozen over again.

Installed 02/01/21 , Just checked Temp. @ everything is working Great. Not hard to change it, as once you open the Cover - Unplug the Timer @ Replace with new Timer. Defrost is working.

Seems to have worked. My freezer would freeze over all the vents and this seemed to have fixed it as I no longer have frozen vents
